Description
Technical Field
The invention relates to the technical field of communication, in particular to an optical fiber distributed access system and a management method thereof.
Background
The optical fiber distributed access system mainly consists of a Main Unit (MU), an Extended Unit (EU), and a subscriber Unit (RU). When capacity expansion and upgrading are needed, only EUs need to be added or changed. The traditional optical fiber distributed access system adopts a master-slave structure, namely, MU is a master station, and EU and RU are slave stations of MU. In order to manage the slave stations, numbers need to be assigned to the master stations and the slave stations so that the corresponding master stations and slave stations can be identified by the numbers.
At present, the numbers are allocated to the master station and the slave stations in a manual allocation mode, namely, the equipment numbers of the slave stations are manually allocated to the master station, and the equipment numbers are set to the slave stations, so that the allocation of the equipment numbers of the slave stations is completed. When a slave station is removed from the optical fiber distributed access system, the device number assigned to the slave station needs to be manually deleted at the master station. When the slave station needs to be reported to the network management center when the slave station is opened, the slave station needs to be manually triggered to access the network management center, namely, the slave station needs to be manually triggered to be opened and removed when being managed.
If a manual mode is adopted to distribute numbers to each slave station and report the numbers to each slave station, the distribution efficiency is low along with the increase of the number of the slave stations accessing the optical fiber distributed access system. And may result in the same number being assigned to two different slave stations, which may be inconvenient for the management of the slave stations.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly and completely understood, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
In the prior art, a manual mode is adopted to distribute numbers to each slave station, and report is triggered to each slave station, and the distribution efficiency is low along with the increase of the number of the slave stations accessing the optical fiber distributed access system. And may result in the same number being assigned to two different slave stations, which may be inconvenient for the management of the slave stations.
In view of this, an embodiment of the present invention provides a management method for an optical fiber distributed access system, in which a master device automatically allocates a device number to a slave device according to information in a management list, such as a serial number or a routing address, so that compared with manual allocation, allocation efficiency is improved, and networking can be flexibly implemented according to the management list.
In the embodiment of the present invention, a device that needs to assign a device number is referred to as a slave device, and a device that is used to assign a number to a slave device is referred to as a master device. Referring to fig. 1, an application scenario of an embodiment of the present invention, that is, an optical fiber distributed access system, is described, where fig. 1 includes a master device and a plurality of slave devices, where the plurality of slave devices are connected in a daisy chain manner to form a plurality of links, and the master device and the plurality of links form a star topology. Fig. 1 is an example including 5 links. The master device may be an MU device, and the slave devices may be an EU device and an RU device, as illustrated in fig. 1, but may be other possible devices.
The following describes a technical solution provided by an embodiment of the present invention with reference to drawings of the specification, and an application scenario shown in fig. 1 is taken as an example in the following description.
Referring to fig. 2, fig. 2 is a flowchart illustrating a management method of an optical fiber distributed access system according to an embodiment of the present invention.
Step S201, the master device sends a request message to each slave device, where the request message is used to request to obtain a sequence number and a routing address of each slave device.
In one embodiment, a plurality of slave devices and a master device are previously deployed into a system as shown in fig. 1. In order to manage the master device and the slave device, numbers need to be assigned to the master device and the slave device to identify the corresponding master device and the slave device by the numbers. According to the embodiment of the invention, the equipment number is automatically allocated to the accessed slave equipment by the master equipment.
Specifically, the master device may send a request message to each slave device that is accessed to request to acquire a serial number and a routing address of each slave device, so as to identify the corresponding slave device through the serial number and/or the routing address, thereby assigning a device number to the slave device.
In a possible implementation manner, after the master device is powered on or reset to start, network topology address information of the optical fiber distributed access system may be acquired, where the network topology address information is used to indicate physical connection positions of the master device and the plurality of slave devices, and a corresponding relationship between the master device or the slave device corresponding to each physical connection position and an IP address of the master device or the slave device, so that the master device may determine the IP addresses of the plurality of slave devices according to the physical connection position and the network topology address information of each slave device. Thus, the master device transmits a request message to each slave device that has acquired the IP address. The embodiment of the invention can send the request messages to the slave station equipment one by one in sequence, and can also send the request messages to each slave station equipment which acquires the IP address at the same time, so as to improve the acquisition efficiency as much as possible.
Step S202, the master station device receives a response message from each slave station device, where the response message carries a sequence number and a routing address of each slave station device.
After receiving the request message, the slave station device may report its own serial number, that is, generate a serial number, a routing address, and the like, to the master station device. If the master station device sends a request message to a plurality of slave station devices at the same time, which may cause the plurality of slave station devices to send response messages to the master station device at the same time, the master station device may miss receiving some of the response messages sent by the slave station devices due to network congestion, and therefore the master station device may send the request messages to the slave station devices one by one in sequence. Or the master station device may send a request message to some slave station devices at the same time, so as to ensure that the acquisition efficiency is improved as much as possible, and avoid that the master station device misses receiving a response message sent by the slave station device as much as possible.
Step S203, for the first slave device, the master device determines whether the sequence number and the routing address in the response message are in the management list, where the first slave device is any one of the plurality of slave devices.
After receiving the response messages sent by the multiple slave station devices, the master station device may assign a device number to the slave station device according to the sequence number and/or the routing address carried in the response messages. Specifically, for example, to assign a device number to any slave device, for example, the first slave device, the master device may assign a device number to the first slave device according to whether the sequence number and the routing address in the response message are in the management list.
It should be noted that the management list is understood as a correspondence table of the serial number, the routing address, and the device number of the slave device, and the management list is maintained by the master device.
And step S204, if the master station device determines that the serial number and the routing address are not in the management list, allocating a new device number to the first slave station device, so as to manage each slave station device through the device number.
When the master station device assigns a device number to the first slave station device, it first determines whether the sequence number and the routing address in the response message are in the management list. If the production serial number and the routing address are not stored in the management list, the first slave station device is considered to be a newly accessed slave station device, at this time, the master station device can allocate an unused device number to the first slave station device, and the first slave station device is set through a device number setting command. And the newly allocated device number is added to the management list together with the serial number and the routing address of the first slave device, so that all the slave devices can be managed conveniently.
If the master station device determines that the serial number of the first slave station device is in the management list, it may be considered that the first slave station device has been previously assigned, and at this time, the master station device may determine whether the device number carried in the response message is consistent with the device number corresponding to the serial number of the first slave station device in the management list, and if so, the master station device does not need to generate a new device number, and may adopt the device number previously assigned by the first slave station device. If the master station device determines that the device number is not consistent with the device number corresponding to the serial number of the first slave station device, it indicates that two device numbers exist in the first slave station device. Therefore, even if the first slave station device is accessed by replacing other slave station devices later, if the serial number of one slave station device is not changed, the serial number initially allocated to the serial number is ensured to be unchanged for the convenience of management, so that the number of the device numbers is small, and the maintenance is convenient.
In a possible embodiment, if the master station device determines that the routing address is in the management list, the state of the device number corresponding to the routing address is determined, and if the state of the device number corresponding to the routing address is determined to be an unallocated state, it may be considered that the device number corresponding to the routing address is not allocated, and at this time, the device number corresponding to the routing address may be allocated to the first slave station device, and at the same time, the serial number of the first slave station device may be updated to the management list. In the embodiment of the invention, the possibility that the slave station equipment is replaced is considered, and the initial equipment number allocated to the slave station equipment can be continuously allocated to the replaced slave station equipment so as to ensure the reutilization of the equipment number as much as possible.
It should be noted that, in the process of assigning the device number to the slave device, if any one of the serial number, the routing address, and the device number is changed, the master device updates the management list, and the management list may further indicate that the device number is in an assigned state or an unassigned state.
The slave device may fail or be damaged during actual use, and is involved in replacement, and the slave device is replaced in the system shown in fig. 1, and its routing address or IP address does not change. Therefore, in the embodiment of the present invention, when the master device determines that there is a certain slave device and, for example, a second slave device is replaced, the serial number of the second slave device may be removed from the management list, and the state of the device number of the second slave device may be set to the unassigned state, so that the master device may assign a newly accessed slave device by using the device number of the second slave device without newly generating a new device number, thereby reducing the number of device numbers as much as possible, reducing the burden on the master device, and facilitating maintenance of a plurality of slave devices.
When the master station device determines that a certain slave station device is removed or fails, for example, the third slave station device, the state of the device number of the third slave station device is set to be in an abnormal state, and the third slave station device which may fail may not be replaced immediately.
In the embodiment of the present invention, the device numbers initially allocated to all the slave devices are considered, but in practice, some slave devices may be removed or have a fault, so that in order to ensure that the number of the device numbers is as small as possible, the device number in the management list with an abnormal state may be allocated to the newly-accessed slave device, so as to facilitate management. Therefore, in the embodiment of the present invention, if it is determined that the number of actually accessed slave devices is less than the full number of device numbers in the management list, which is the total number of the maximum slave devices simultaneously connected to the master device, the master device allocates a device number in an abnormal state in the management list to the newly accessed slave device.
For example, currently, the number of slave devices accessed by a general master device is 32, and when the number of devices in the management list is 32, that is, the number of devices allocated by the management list is full, but the number of devices actually accessed to the slave device is less than 32, the master device may allocate the number of devices in the management list, which is in an abnormal state, to a newly accessed device in order.
In the embodiment of the invention, the master station equipment can also report the states of the slave station equipment and the like to the network management center. Specifically, the master station device may periodically query the state of the slave station device in the management list, and if it is determined that the state of the slave station device is a normal state and is not reported by a network operator, send a request for opening the network operator to the network management center, so as to notify the network management center to update the information of the slave station device. Of course, if there is a slave station device removed, the master station device may trigger and report the removal to the network management center.
It should be noted that, the embodiment of the present invention takes the secondary architecture shown in fig. 1 as an example, and in essence, the embodiment of the present invention may also be applied to a tertiary architecture, that is, a master device accesses an extension unit, and each extension unit may access a remote device, where the remote device may be regarded as a slave device of the extension unit, and the extension unit is a slave device of the master device.
In summary, in the embodiment of the present invention, the master device automatically allocates a device number to the slave device according to the information in the management list, for example, the serial number or the routing address, which improves allocation efficiency compared with manual allocation, and can flexibly implement networking according to the management list.
